If anyone is watching Still Game through for the first time I strongly advise to stop here. There is a massive drop in quality in the show after this season (the result of a fallout between the 2 stars of the show) and when it was brought back to air it was a shadow of it's former self, with the honourable exception of the last 2 episodes. It's best just to re-watch the show up to this point and enjoy what it once was
